The latest episode of the Robots podcast takes a closer look at the emergence of communication - and how it can be studied using robots. The first part features an interview with Sara Mitri, an interdisciplinary researcher at Switzerland's EPFL and the University of Lausanne, Switzerland. Mitri and colleagues have taken an unusual approach to the problem: Using the ground-based S-Bot robots (pictured above) as a model for biological organisms, they used artificial evolution to study complex behaviors like communication. And as the broad media coverage of her recent publications in Current Biology and PNAS show, the advantages of this approach have not gone unnoticed: While retaining many of the real-world complexities present in biological systems, the robotic models allow complete access to all model parameters. And there is another key advantage: Today very little is known about the evolution of phenomena like communication, because they leave no trace in the fossil record. By conducting artificial evolution, this work allowed to reconstruct part of that missing evolutionary history and shed light on the origins of communication in all animals, from simple cells to us humans. In the second part of the podcast, Jürgen Jost, director of the "Complex Structures in Biology and Cognition" group at Leipzig's Max Planck Institute discusses the question of intentionality of robot communication.

Portable Laptop
A laptop is a personal computer designed for mobile use and small and light enough to sit on one's lap while in use.[1] A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick), speakers, and often including a battery, into a single small and light unit. The rechargeable battery (if present) is charged from an AC adapter and typically stores enough energy to run the laptop for two to three hours in its initial state, depending on the configuration and power management of the computer.Laptops are usually shaped like a large notebook with thicknesses between 0.7–1.5 inches (18–38 mm) and dimensions ranging from 10x8 inches (27x22cm, 13" display) to 15x11 inches (39x28cm, 17" display) and up. Modern laptops weigh 3 to 12 pounds (1.4 to 5.4 kg); older laptops were usually heavier. Most laptops are designed in the flip form factor to protect the screen and the keyboard when closed. Modern tablet laptops have a complex joint between the keyboard housing and the display, permitting the display panel to swivel and then lie flat on the keyboard housing. They usually have a touchscreen display and some include handwriting recognition or graphics drawing capability.
Laptops were originally considered to be "a small niche market" and were thought suitable mostly for "specialized field applications" such as "the military, the Internal Revenue Service, accountants and sales representatives". But today, there are already more laptops than desktops in businesses, and laptops are becoming obligatory for student use and more popular for general use. In 2008 more laptops than desktops were sold in the US and it has been predicted that the same milestone will be reached in the worldwide market as soon as late 2009.
